Super scientist Nina and her young Experimenters travel the UK in search of sporting wonders. With the help of Nina's five animated sense Neurons, they explain why sports people are so amazing and how we can all get out and get sporty.

Nina investigates how we swim - with the help of Felix, her touch neuron.

Experimenters Nina and Olivia visit Nina in her lab and discover that we use our arms to pull us through the water when we swim. Next, they have a go at swimming themselves and find out that our legs push us through the water. Finally they meet some swimmers and see that they use their arms and legs in different ways for different strokes. Show less
